Non-suicidal self-harm (NSSI) is the behavior that an individual will not take suicide as the purpose, to harm their own body, and will not be recognized by the society. This behavior will mainly produce very serious negative consequences, which has been widely valued by the parents of university hospitals. According to previous studies, the incidence of NSSI is relatively high in early adolescence, and the existence of non-suicidal NSSI behaviors among college students is also highly universal. College students have certain particularity, and belong to the group of collective life, their own education level is relatively high, with personality and ideal. In recent years, the number of NSSI among college students has been further increased, and NSSI has also received wide attention from scholars. The detection rate of NSSI among Chinese college students has reached 16.6%. Although in essence, the actual purpose of NSSI is not suicide, the behavior also represents that individuals are prone to various types of psychological and spiritual problems. Based on the above perspectives, this paper analyzes the behavior of NSSI of college students, and explores the influencing factors. We hope that on this basis, Chinese college students can pay attention to NSSI related problems, and the mental health of college students can be effectively improved [1].
